Tripod might help dampen it enough, so that's a good start. I'm using the ATLAS Super CAL and it works fairly well. I had to swap the plastic bushing for a brass one because the plastic one kept smashing itself out of shape due to the weight of the rifle.
You should order a second picatinny lower rail for the tremor. It only comes with one. Then you don't have to move it for use with tripod or bipod. It's a special type that only works on the Tremor chassis on the underside. The side picatinny rails are different mounting types and don't have the durability.

That's a reasonable price for M33. Some places you can get it sub $3. I picked up a bunch of PMC for about $2.50 a round. M33 is reasonable out to 700 yards on a full size IPSC plate. I'd say I get a 50% hit rate.
If you are plinking close range, just remember the mil M33 cores are mild steel and won't as easily disintegrate on impact like lead core. More chance of ricochet off dirt and objects, more penetrating power through whatever backstop you use. At 1k yards its still got 3,700 ft lb of energy, 500 yards is 6,500 ft lb, 100 yards 9,800 ft lb! It's not uncommon for me to knock down the local range steel targets. Thankfully the owner is all on board with people shooting 50's out there.
I've tried the 7-35 shooting another range members rifle. Unless you are shooting a low recoil caliber, it didn't seem helpful to go 35x. I almost never go 25x with my tremor because spotting hits becomes more difficult.
